The Sun is a ball of glowing gases, a star at the centre of our Solar System. Its diameter is about 1.39 million kilometres, or more than 100 times the diameter of Earth. However, the Sun is a small star compared to other known stars in the sky, such as Antares in the constellation Scorpius, which is a giant star with a diameter of about 450.000.000.000 km.

Our Sun is a so-called yellow star and is composed of 73% Hydrogen, 25% helium and 2% heavier elements, giving it a density of only a quarter of Earth’s, despite its size.
